VENDLQ'G-EETE'E.

Application filled June 29,

. Des Moinee, in the county or: Polls and State oi lowa have invented certain new and useful Improvements in Vending-Meters, or which the following is a specification.

This invention relates to vending meters and more particularly to a coin controlled device the kind intended primarily for measuring the amount of water that flows through a ipe.

With thrs and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described in the following s cification, pointed out in the claim and il ustrated in the accompanying drawings which form a can of said specification and in which Figure l is a front elevation, partly in section, of; the met-er. Fig. 2 is a detail of the measuring tape used. Fig. 3 is a vertical crew section or the meter taken on line 33 of Fig. 1. Fig. i is a horizontal section giving a plan view of one tape Fig; 5 is a detail of the vertical rack employed. Fi 6 is a plan of the automatic cut-0E employs Lil ie reference characters indicate corresponding parts throughout the several views.

2 is a water pipe through the water to be measured flows. This pipe extends through and beyond a meter casing 3 5, dpreferably near the floor 3 thereo 3 is a gage glass arranged. in hthe casing.

7 is a vertical rack secured to a plate a, which plate 8 is in turn secured to the end 6 of the casing, in such a manner that it is capalole of movement vertically; this rack is provided with a head 9 on one end which receives a lever 10 pivoted as at 11 in the end 6 or" the meter. A spring 9 secured in the casing yieldingly holds lever 10 against the head of the rack.

12 is a cog-wheel arranged on a hub 13 which is secured to a shaft 13 journaled in the sides a, b, of the meter casing and its teeth work over the teeth of the vertical rack 7 to raise and lower the same vertically.

14 is a tape spool arranged on hub 13*. ape 15 having the measuring scale marked thereon has one end secured to the spool 14% from which spool it runs up and over a specification 01* Letters Patent.

pair or pulleys 16, is secured in a recess 1.? is the top 5 oi the casing, and down and over another tape spool 13 arranged on hub 19 secured to the shatt 19 jourealejd in the sides a, b, or the casing 20 is a pawl arranged on a pivot 21; in

sides a, F), of the casing and having a 22 attached to one end, the other end or the spring being secured to the end a oi the casing. 'lha free endof this awl is adapted to slide over the teeth of wheel 23 secured on hub 19 and to permit rotation of the same freely in a direction that will wind the tape upon the spool 18 but to o er a slight resistance to a reverse motion so that a slight jarring of the box would not render the mechanism inoperative;

24 is a cog-wheel arranged on huh l9 and adapted to impart intermittent motion to as the same through contact with an upright arm 25; arm 25 being movably secured to a plate 26 which plate is secured to the ends of the casing. The lower-end of arm 25 has a spring 27 secured thereto, the op site and of the spring being attached to a ng'or 28 depending from the bottom or" plate 28.

29 is a serrated power wheel having a projection 30 arranged on the circumference which projection is adapted for engagement with the lower extremity of arm as with each revolution. of wheel 29.

31 is a water-wheel arranged on a ehedt 32 which is journaled in a pocket 33 arranged transversely of the water pipe 2,

i'ne extremity of shaft 32 carries a pinion 34 that meshes with another pinion 35 an ranged on a stub shaft 36 secured to pocket 33, this last named pinion meshing with the power-wheel 29 and driving the same.

Referring again to the water pipe 2 the same is provided with an automatic shut-0d the description of Which follows: 37 is a casing surrounding the ipe 2 and support ing a damper that residgs within the water pipe, whose vertical diameter is approximately three-fifths the vertical diameter of the water pipe, which damperhas a serrated handle 38 projecting up through the top of the casing 37. 39, 39 are a pair of brackets secured to the side 6 of the meter casing adjacent the plate 8 and afiording bearings for a pair of shafts 40 and 41. These shafts" each carry one member of a spur gear 42, one member of this gear meshing with the vertical rack '4'. One end of shaft 41 is further provided with a spur 43 that meshes with the handle 38 of the damper and at- I the water.

fords a means of ralsing or lowering this damper in the water pipe. 44 is a coin box secured to the meter casing and having an opening 45 in the top thereof to admit the coin. A hood 4:6 is arranged on the meter casing near the coin box and over an opening 47 in the casing through the latter and into the former of which the rack 7 is adapted to pass while the mechanism is in operation. 48 is a handle extending out through the side b of the meter casing and connected. by belt d9 with hub 13 on which tape spool 14 is arranged and which hub is secured to the shaft 13. This handle is to wind the tape on the s 001' after the same has been unwound by t e operation of the meter and through the medium of cog-wheel 12 to raise rack 7 well'up into the hood 4C6 which lifts the damper and permits free flow of Operation: In the position shown in Fig. 1 the supplyof water is shut ofi. By dropping a coin in the opening 45 of the coin box the same strikes the lever 10 and raises it against the tension of spring 9 from the rack head, The operator must now grasp the handle 48 and turn the same to the left. This operation will wind the tape upon the spool 14 and unwind it from spool 18 and at the same time it will raise the rack 7 vertically as high as it can go thus opening the water pipe. The water runnin through this 'pipe will 'turn the water whee 31 which by its connections will turn power wheel 29 which through the medium of arm 25 will impart intermittent motion to the shaft 19 which will wind the tape 15 upon the s 001 1% arranged on that shaft thus unwin ing it from spool let, turnin shaft 13 with cog wheel l2 thereon whic gradually lowers i sane rack 7 until this rack through contact with the mechanism shown in Fig. 6 will auto matically shut ed the supply of water when the coin inserted will have been spent and the machine will be once more in position for another coin. A suitable opening is provided in the coin box for the removal of the coins deposited What is claimed isi In a coin controlled device, an apertured casing having a hood disposed over one aperture a coin receiving box disposed upon said casing over another aperture therein, a spring-pressed lever pivoted in the :w tured ortion of said casing and extening into tide said coin box, arack slidably secured within said casing normall tact with said lever, a serrated w eel journaled in the casing and provided with a. circumferential projection, means for actuating said Wheel, cut-ofi means for the said wheel-actuating mechanism operable by said sliding rack, tape-connected spools mounted within the casing operatively engaging said sliding rack, mechanism secured to the casing capable of intermittent engagement with the circumferential projection of the said serrated wheel whereby, an interrupted motion is imparted to the said spools and to the said sliding rack and manually operable means for reversing the interrupted motion of said spools and sliding rack.
